STUDY ON THE GREEN-SHADE SELECTION BEHAVIOR OF PARK USERS UNDER HIGH SUMMER TEMPERATURES

Abstract

 In Osaka Municipal Nagai Park, we investigated the relation between user's green selection behavior and thermal environment in summer heat environment. As a result, it was found that under the hot environment where WBGT exceeds 27.5 °C, the proportion of pedestrians who select greenshade bushes increases by 2.2 - 2.4% when WBGT rises by 1.0 °C. Regarding the runner, the proportion of choosing the sidewalk shade increased by 4.5 - 5.5% when WBGT rose by 1.0 °C., and conversely the proportion of choosing the roadway shade decreased. Also, people who do not usually use the park tend to select shade at a higher rate than people who use the park everyday. With WBGT exceeding 30.0 °C, over 90% of people were selecting the shade despite being detouring against the destination. When providing services to people who do not do much outdoor activities, it is necessary to provide more shade space.
